It's because x86 and sparc64 seem to get the ipv6 checksum header
implicitly somehow.

I'll fix this as follows, thanks for the report Stephen:

cnic: Need to include net/ip6_checksum.h

drivers/net/cnic.c: In function 'cnic_init_storm_conn_bufs':
drivers/net/cnic.c:1757: error: implicit declaration of function 'csum_ipv6_magic'
